whoami

[Ramesh_20]

Hi,
I am having a weird problem in linux boxes. They are behaving indifferently to the whoami command. When i type whoami its showing a different username and also the terminal pts/2 for 5 or 6 users. I understand that each user needs to be assigned a different terminal like pts/1 pts/2 etc...but how come one tty pts/2 is used for too many users. Is that affecting the whoami to display the correct user? Any help appreciated

It could be normal if all of them are connected remote to your linux box. Is it the case ?

But i am logged in as user-1 and but it is showing as user-2!!!We are having problems while executing some scripts for monitoring and totally that screws up entire stuff

Check user-1 and user-2 uid in /etc/passwd or /etc/shadow, and check with 'who', 'w' and 'users' who the system sees as logged in.

There seems to be a mess with your authentication. Are you logged local or remote ?

Sounds like your /var/run/utmp is up the creek.

'who', 'w', 'whoami', 'last', and all of those sorts of tools use /var/run/utmp to keep track user logins.

Oh sugar. Forgot to say how to fix it :P

Get everybody off the machine, zero out the file (move it aside is probably best), sign in and check again.
